WHEELWR-IGHT-MACHINE.

Specification of Letters Patent. Patented Sept. 17, 1912.

Application filed May 21, 1910. Serial No. 562,756.

To all whom it may concern:

'Be it known that I, CHARLES L. BRINK, a residing at Lansing, in thecounty. of Ingham and State of Michigan, have invented certain new anduseful Improvements in Wheelwright-Machines, of which the following is aspecification..

My invention relates to power wrenches and while it may be used formany'purposes it is more specifically designed for the purpose offacilitating the manufacture of Wheels for automobiles and other roadvehicles. -In the manufacture of such wheels it is found desirable totemporarily fasten the spokes together by the use of what is known as adummy hub which is composed of two parts adapted to screw together andmy device isprimarily designed for the purpose of screwing together thetwo parts of these dummy hubs after the spokes have been placed inposition.

In the drawings, Figure 1 is a plan view of my device; Fig. 2 is anelevation from the front; Fig. 3 is an elevation taken from the endopposite the driving pulley, and Fig. 4 is an elevation of the dummyhub.

Referring more particularly to the drawings, 1 is the main frame of mydevice which may be of any desired construction adapted to support theworking parts and may be adapted to either stand on the floor as shownin the drawings, or to be suspended from the ceiling. A wheel press 2,an elevation of which is shown in Fig. 2, is supported on the lowermember 3 of the frame in a bearing 4, so that it can be readilyrevolved. The radial arms, 5, of this press are united by a ring Q, onwhich are mounted screws 7 equal in number to the spokes of the proposedwheel, each of said screws being provided with a handle 8 for operatingit, and a socket, at the opposite end, formed to fit the end of thespoke. The hub support 10 is mounted on a screw shaft 11 subthe dummyhub firmly pressed against the hub support 10.

A revolving shaft 17 carries at its lower extremity a wrench 18, adaptedto fit a nut 19 on the second half of the dummy hub. This wrench isfirmly secured to the shaft 17 by a set screw 20 or in any othersuitable manner so as to be removed when desired. The shaft 17 passesslidably through the upper member 21 of the frame 1 and also through amain gear 22 to which it is splined or otherwise connected, so as torevolve with the said gear, but at the same t11 1l6 to be readilyraisedand lowered. The

gear 22 is supported on a bearing 23 formed on the upper surface of theframe and is driven by a pinion 24, actuated by the pulley 27 and shaft28 through a friction clutch 25, which may be of any desiredconstruction and is operated by a lever 26, in the usual manner. Theshaft 17 is raised and lowered by a lever 29 which lever carries acounter weight 30 which is heavy enough to overbalance the weight of theshaft and lever so that normally the shaft will be held raised to itshighest point, but may be drawn down by pulling on the handle 31.

The operation of my device is as follows: The lower half 16 of the dummyhub is first placed in position on the hub support 10 and secured thereby screwing down the hut 15. The spokes are then placed in position andpressed firmly together by the screws 7. It is evident, however, thatinstead of the screws 7, many other well known means of pressing spokesinto position, either separately or simultaneously, might be employedwithout departing from my invention. The spokes having been placed inposition, the upper half of the nut 19 of the dummy hub is screwed onthe thread 32 cut on the lower half 16 of the hub, the friction clutchis then brought into engagement by means of the handle 26, and therevolving shaft 17 is lowered by drawing on the handle 31 until thewrench 18 engages with the nut 19, when the nut will be screwed downuntil the spokes are firmly clasped between the flanges 33 and 34 of thedummy hub. The friction clutch 25 is so adjusted that it will slip whenthe nut 19 is screwed down sufficiently, and thus prevent the machinefrom being broken or the belt on the pulley 27 from slipping. A stop 35is adapted to engage with the wheel press 2, so as to prevent it fromrevolving when the wrench is brought into action, and at thehorizontally, a hub support at the center of the press, means forclamping one member of an adjustable hub to the hub support and rigidwith the rotatable press, means for holding and adjusting wheel Spokesto a hub on the hub support, said means comprising a plurality of screwclamps mounted around the outer part of the press, each screw clampbeing provided with a socket to receive the outer end ofa spoke, awrench mounted in the frame above the hub support, said wrench beingsadjustable to and from the support for turning a hub member, which has ascrew threaded engagement with the hub member that is clamped to the hubsupport, to tightly clamp the wheel spokes between said hub members, astop movable into engagement with the wheel press to prevent-the wheelpress from rea volving', when the wrench is operatingv on the adjustablehub member, and means for operating and adjusting the wrench.

In testimony whereof I affix my signature in the presence of twowitnesses;
